[SOLVED] Creating primary key from query.

Hi There, In Task1 : Could you please check the error in my query? I don't know how to place the name of the primary key here.

Challenge Task 1 of 3

Create a genres table called "t_genres" with an auto incrementing primary key called "pk_id" and a unique column called "uk_name" that can't be null. The "uk_name" is a varchar of up to 45 characters. Type in your command below, then press Enter.

My query : 

CREATE TABLE genres (t_genres AUTO_INCREMENT PRIMARY KEY, uk_name NOT NULL UNIQUE KEY);

As I can see from task, you need table t_genres:

CREATE TABLE t_genres 
(pk_id INT(6) AUTO_INCREMENT PRIMARY KEY, 
uk_name VARCHAR(45) NOT NULL UNIQUE KEY);

You need also specify type of column (such as INT. or VARCHAR...)
